Abstract

A method for manufacturing golf club head is provided in present invention by which degraded product can be prevented when manufacturing. The golf club head comprises: a head body (1A) made of metal material having at least one opening part (O1) at top face part thereof; a top face part component (1B) made of metal material and fixed on the head body (1A). The head body (1A) comprises: a supporting part (10b) for supporting the inner face (1Bi) circumference part of the top face part component around the opening part; a projecting part (10c) projecting outward which is provided along the outer circumference (1Be) of the top face part component (1B). The method further includes the following steps: a temporary fixing step by which the top face part component (1B) is supported and covered by the supporting part (10b) so as to plastically deform the projecting part (10c), thus a press bending part (10d) is formed which sandwiches the top face part component (1B) between the supporting part (10b) and press bending part; a formal fixing step for fixing the head body (1A) with the top face part component (1B) after the temporary fixing step.

Description

Golf club head and manufacturing method thereof technical field The present invention relates to a golf club head capable of reducing the occurrence of defective products during manufacture and a method for manufacturing the same. Background technique Conventionally, a golf club head has been proposed in which a head body having an opening in the top surface and a top surface member that is made of a metal material different from the head body and closes the opening are provided. A hollow structure to be joined. However, in such a club head, misalignment is likely to occur when the club head body and the crown surface member are joined, and as a result, the club head is prone to unsightly appearance and durability degradation due to poor joining. In addition, for example, such a technique has also been proposed. As shown in FIG. 19(A), (B) and the C-C section of FIG. 19(B), that is, as shown in FIG. In the case of head a, a convex part c is provided at the joint end of ...
